Blewązka, zbiornik zaporowy

Blewązka is a reservoir located west of Kobyla Góra on the Wzgórza Ostrzeszowskie hills, created between 1972 and 1983 by damming the Meresznica stream. Spanning approximately 900 meters in length with a maximum width of 520 meters and reaching depths of about 7 meters, the roughly 18-hectare water body is surrounded by pine forest and features a sandy beach along its shoreline.

The reservoir was created between 1972 and 1983 by damming the Meresznica stream. The site had earlier been a rallying point: in 1848 insurgents gathered under Tomasz Sikorski, a peasant from Ligota, and a monument by the dam commemorates this. The nearby Jewish cemetery in Kobyla Góra holds numerous surviving matzevot.

The reservoir, also known as Zalew Kobyla Góra, serves as a gathering place for the local community. People come here to swim, fish, and participate in water sports, making it a social hub where families and friends spend leisure time together throughout the year.

The reservoir lies in the western part of Kobyla Góra, in Ostrzeszów County, Greater Poland. The shore has a beach, eateries, boat rentals, sports facilities and hotel accommodation. The Orion sailing club and a windsurfing school are based here, and the reservoir is stocked mainly with carp and hosts angling competitions.

The Orion sailing club based here offers windsurfing courses and sailing activities that draw water sports enthusiasts. The reservoir is regularly stocked with fish, particularly carp, making it a popular destination for anglers who fish throughout the seasons.
